About Dwyer 4002 Capsuhelic Differential Pressure Gauge

Capsuhelic Differential Press. Gauge, 0-2 in H2O, brass case

Differential Pressure Gage, Range 0-2.0" w.c., For Vertical Scale Position Only.

The Capsuhelic gauge is designed to give fast, accurate indication of differential pressures. The gauge may be used as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and many other applications involving pressure, vacuum or differential pressure. Using the basic design of Dwyer's time-proven Magnehelic gauge, the Capsuhelic gauge contains a simple, frictionless movement that permits full scale readings as low as 0.5 in H2O. The pressure being measured is held within a capsule which is an integral part of the gauge. This containment of the pressure permits the use of the gauge on system pressures of up to 500 psig, even when differentials to be read are less than 0.1 in H2O. The diaphragm-actuated Capsuhelic gauge requires no filling liquid which might limit its outdoor applications. Zero and range adjustments are made from outside the gauge, and there is no need to disassemble the gauge in normal service. Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Robust Industrial Design

The Dwyer 4002 Capsuhelic Gauge is engineered for demanding industrial environments. Its rugged black case, precision-molded housing, and IP54 enclosure rating deliver durability and resistance to dust and limited moisture. The gauges materials, including acrylic, aluminum, and Buna-N, ensure longevity and reliable performance, even under constant use.

Clear, Accurate Display

Featuring a 4-inch diameter analog display, the gauge offers a clear view of pressure differentials with a scale range from 0 to 2 inches H2O. The white aluminum dial with black markings and a black aluminum pointer make readings simple and precise. With 2% full-scale accuracy, users can trust the results in critical applications.

Simple Installation and Adjustment

The 4002 Capsuhelic includes mounting brackets and screws for hassle-free surface or panel installation. Its external screw-type zero adjustment makes recalibration easy without disassembling the unit, saving time and effort during maintenance routines. The 1/8" NPT connections allow secure attachment to pressure sources.

FAQs of Dwyer 4002 Capsuhelic Differential Pressure Gauge:

Q: How do I install the Dwyer 4002 Capsuhelic Differential Pressure Gauge?

A: This gauge can be mounted on a panel or surface using the supplied mounting bracket and screws. Simply connect the high and low pressure lines to the 1/8" female NPT ports, and ensure the gauge is securely fastened for accurate readings.

Q: What gases can I measure using the Capsuhelic 4002 gauge?

A: The gauge is suitable for measuring differential pressure in non-corrosive gases only. Using it with corrosive gases may damage the internal components and affect accuracy.

Q: When should I use the zero adjustment screw?

A: Use the external zero adjustment screw before initial operation or after any significant pressure fluctuation to calibrate the needle to zero. This ensures measurement accuracy and reliability.

Q: Where can the Capsuhelic 4002 gauge be used?

A: This model is designed for industrial applicationsHVAC systems, filtration monitoring, or process controlsanywhere non-corrosive gas differential pressure needs monitoring within a temperature range of 20 to 120F.

Q: What is the process for reading the pressure value on this device?

A: Simply observe the analog pointer against the clearly marked scale, which ranges from 0 to 2 inches H2O. The pressure differential is indicated directly without conversion.

Q: What are the benefits of using an analog display for differential pressure readings?

A: An analog display allows for quick visual checks, trend observation, and does not require power to operate, making it robust in power-sensitive environments.
